hs2p backend update

<jazz_johnson <at> verizon.net>

The hs2p backend is basically finished, except for adding support for
continuous scanning and support for uploading custom halftone patterns
and gamma vectors. I do not plan to add support for reading/changing IPU
parameters since I don't have a scanner with such an option. Nor do I plan
on adding support for reading/changing maintenance data, which is only
necessary when a technician changes the lamp or ADF unit, and would
probably be more appropriate in a stand-alone calibration utility.
I'm trying to add support for uploading custom gamma tables to the scanner
using OPT_CUSTOM_GAMMA boolean and OPT_GAMMA_VECTOR word array
following code from backends which implement custom gamma vectors.
For some reason I'm not seeing a window with a plot of the gamma curve
that I can edit with the mouse. Maybe I've missed something.
I've written a hs2p.desc and sane-hs2p.man file and made
modifications to sane.man and doc/Makefile.in
When I build the 'make html-pages' though I don't seem to generate
the sane-hs2p.5 file.
I've placed a tarball for the hs2p backend at
http://www.acjlaw.net:8080/~jeremy/Ricoh/hs2p_sane_backend/hs2p.tar.bz2
which includes the following files:
tar -cvjf hs2p.tar.bz2 \
sane-backends-1.0.18/configure.in \
sane-backends-1.0.18/backend/hs2p-saneopts.h \
sane-backends-1.0.18/backend/hs2p-scsi.h \
sane-backends-1.0.18/backend/hs2p.h \

Small progress!
0x00b0 0x96 xx 0x96 xx seems changing lamp state:
"0x01" - turn off, and "0x01 <" - turn on.
This command is working even if scanner is turned off, when i send
command "0x96 0x21 0x96 0x21" lamp start lighting, but power led on
scanner still off!!!
If send "0x96 0x01 0x96 0x01" then lamp is switched off and power led
still staying off.
It is normal? Others scanners behave in the same way?
Also i have tried to find command which returned lamp status, but all
attempts have failed.

please see:
http://www.sane-project.org/contrib.html
there are some links there to get you started, and you can always ask
on this list for more help, but you are going to have to do most of
the work, since you have access to the hardware.

Hi Everyone
This is my first post. I am hoping to assist in writing
scanner/printer/vinyl cutter backends in Linux.
I was thinking about buying software form this company:
http://www.hhdsoftware.com/Products/home/usb-monitor.html
They have a closed source App that logs the communications between
different USB device's and Windows. Once the commands are know
presumably they can be ported to Linux.
Is there and open source equivalent for this program? Is this how the
communications are normally captured? Is there and easier way to do this.
Thanks-Patrick
